Accupro ACC-BB2301600 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB2301600 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes, machining centers, and manual turning equipment. Built from submicron-grade carbide with a bright finish coating, this bar delivers the rigidity and wear resistance needed for tight-tolerance bore work. It accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 1.6 inches, making it well suited for shallow to moderate-depth finishing passes in small-diameter bores. Machinists and toolroom technicians working with ferrous and non-ferrous materials will find the bright, uncoated carbide surface appropriate for a wide range of workpiece materials.

This boring bar is used in production and job-shop environments where small-bore accuracy is critical. The right-hand cutting direction is compatible with standard spindle rotation on most conventional and CNC turning setups. The 5/16-inch shank diameter fits standard boring bar holders and tool blocks commonly found in light-duty turning centers and bench lathes. It is a practical choice for repair shops, toolrooms, and production cells requiring consistent, repeatable bore geometry in small-diameter features.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Bright finish coating — no additional coating buildup on cutting edge, preserving sharp geometry
• Minimum bore diameter of 0.23 inches for access to small-diameter bores
• Maximum bore depth of 1.6 inches suitable for shallow to moderate bore depths
• Right-hand cut configuration compatible with standard spindle rotation
• 5/16-inch shank diameter fits common boring bar holders and tool blocks

Compatibility

Designed as an OEM-style replacement and standard tooling solution for boring bar holders accepting a 5/16-inch shank diameter in right-hand turning configurations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing or adjusting tooling. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping procedure, minimizing overhang to reduce chatter. Verify workpiece setup and bore alignment before taking the first cut.
